Title: Weaving machine - has arrangement of swivel guides for warps to give increased range of fabric structures
IPC: D04B39/06
Filed: 1979-01-19
Abstract: The machine to produce woven goods from a number of threads, yarns or wires, has swivel guides for the warps mounted to a fixed pivot with a number of eyes either closed or open on one side. There is a special guide needle with the swivel guides and a moving control element of the machine acts on the control butts of the swivel guides. The moving yarn guide together with the control element brings a knitting yarn below or above the lifting arm of the swivel guide across the feed direction of the warps. This is done together with a gripper to lay the wefts in the sheds so formed above or below the swivel guides, or an air jet or magnet projectile can lay the weft. There is >=1 needle bed above the machine carrier to form the stitches of the knitting yarn and the warps, or only the warps under the lifting arm. The machine gives a greater variety of woven fabric structures than can be achieved with a loom, knitter or warp knitter, with high prodn. and low-noise operation.

Title: Gas-tight-sealing mould section joints for polyurethane foam objects - by hollow PTFE body inflated by pressurised medium
Inventor: BAXMANN HELMUT
IPC: F16J15/46
Filed: 1979-06-05
Abstract: An elastic hose of "Teflon" (RTM) filled with a fluid or a gas, is arranged so that it can act on the sealing edges of the sections of a divided mould, which can be locked together. Pressure is applied to the medium in the hose and as the cross-section alters, the sealing edges of the mould sections are made gas tight. The process is applied in partic. to the prodn. of foamed mouldings. After the sealing of the edges, the mould is filled through a casting inlet with polyurethane soft foam. A high vacuum is laid on to the casting inlet so that the closed cells of the foam structure burst, filling out the moulding, which is ejected and exposed to the air, after the hose has been detented. For the production of mouldings of soft polyurethane foam for upholstery in the furniture and automobile industries. The invention ensures a gas tight closing of the mould edges. The formation of spewed ribs along the joint lines is prevented since leakage cannot occur. The time consuming work of trimming off the flash with possible damage to the mouldings is eliminated.

Title: Vehicle IC engine with turbocharger - has manual control to give choice of turbocharger control modes for different driving conditions
Inventor: SCHUMANN GERHARD DIPL ING
IPC: F02B37/18
Filed: 1979-07-13
Abstract: The engine has a turbocharger in which a turbine driven by the exhaust is coupled to a compressor which delivers air to the engine. There is a bypass round the turbine. The bypass is controlled by the compressor discharge pressure and opens when this pressure exceeds a preset value. It has a further control from the pressure downstream of the engine throttle and opens when this pressure falls below a preset value. A valve operated manually by the driver disconnects the second control. This increases the accelerating response of the engine at the cost of efficiency when such performance is required.

Title: Indicating sections of frequency band in use - Pulse-width modulating multivibrator triggered by TV line frequency for TV screen display
Inventor: WRAASE VOLKER
IPC: H03J7/32
Filed: 1979-07-24
Abstract: The display system uses demodulated output from a swept receiver for pulse-width modulating a multivibrator triggered by the t.v. line frequency.

Frequency markers are also blended into the display. The system can be used to display two occupancy diagrams on the same screen if two receive channels and two pulse-width modulators are incorporated. The system can be operated from an antenna (also used for transmission) if a change-over device controlled by a h.f. voltage is provided.
